Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Initializes a new instance of the SafeHandle class with the specified invalid handle value.

protected:
 SafeHandle(IntPtr invalidHandleValue, bool ownsHandle);

protected SafeHandle (IntPtr invalidHandleValue, bool ownsHandle);

new System.Runtime.InteropServices.SafeHandle : nativeint * bool -> System.Runtime.InteropServices.SafeHandle

Protected Sub New (invalidHandleValue As IntPtr, ownsHandle As Boolean)

Parameters

invalidHandleValue: IntPtr
nativeint

The value of an invalid handle (usually 0 or -1). Your implementation of IsInvalid should return true for this value.

ownsHandle: Boolean

true to reliably let SafeHandle release the handle during the finalization phase; otherwise, false (not recommended).

Exceptions

TypeLoadException

The derived class resides in an assembly without unmanaged code access permission.

Remarks

If the ownsHandle parameter is false, ReleaseHandle is never called; thus, it is not recommended to use this parameter value as your code may leak resources.
